This patch> automatically generates a warning for any new system call which is> implemented on i386 but not the architecture currently being compiled.> On PowerPC at the moment, for example, it results in these warnings:> init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented> init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented> init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented
